Benzoic acid derivative having vinyl group at the p-position through methylene spacer was synthesized Mixture of the benzoic acidderivative 4,4'-bipyridne (2:1 molar ratio) was found to show a smectic phase in the range of 89℃ to 113℃. Polymerization of the mixture was carried out by using 0.5wt% of 2,2-dimethoxy-2-phenyl-acetophenone as a photoradical imitator. Conversion of the mixture was more than 90% by UV irradiation for 5min at the smectic phase. The smectic phase was maintained after photopolyrrmerization.
